To LH whom, 1125 ntcty concern:

Be it known that I, GEORGE W. MCGILL, of the city of Buffalo, in thecounty of Erie and State of New York, have invented a new and ImprovedMode of Fastening Doors, whether opening-from without or from within;and I do hereby declare that the following is a full and exactdescription thereof7 reference being had tothe accompanying drawings,and to the letters of reference marked thereon.

The nature of myinvention consists in the construction of adoor-fastener which maybe conveniently carried about ones person as asubstitute for locks,bolts, dac., and which can be attached to anydescription ot' door, whether opening in or from a room, withoutdifficulty.

'lo euableothers skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

Figure l in the accompanying drawings represents the article closed.Fig. 2 represents the fastener as applied to a door which opens out froma room.

The teeth ct a on the crooked blade B are pushed into the door Z. Thethumb-screw O is then drawn into the socket d and the door is pulled to.

Blade B being shaped to the jalnb of the door allows it to shut. Thegimlet-pointed screw C is then screwed into the jarnb and the door issecure; but should the door open into a room the teeth H H on blade I,Fig. 3, are pushed into the jamb of the door K. The thumb-screw Lisscrewed to one side and the door is closed. The thumb-screw L is thenscrewed out across both jamb and door and secures the door from beingpushed in.

The bladesB and I are secured together by the socket d, and the ange Oon the thumbscrew C holds it in the socket d.

Having thus fully described the nature, construction, and operation ofmy invention,

I will now proceed to state what I claim and desire to secure by LettersPatent:

l. The formation of blade B, with its peculiar connection with blade I.

2. The use ot' the blade B, constructed as described and operating inconnection with screw L and blade I and screw C, for the purposespecified.
